2016-7-21 The compressive strength values of the cube specimens at the age of 28 days are as shown in fig 3. It has been observed that the compressive strength of concrete for the cubes with polypropylene fiber 1%, 1.50% and 2% is more than that of cubes without polypropylene fiber 26 N/mm2, 26.40 N/mm2 and 28 N/mm2 respectively compare with control mix without polypropylene fiber as compressive strength was 25 N/mm2. This may be due to the fact that the polypropylene fiber will effectively hold the micro cracks in concrete mass. The percentage increase in the compressive strength for the cubes with polypropylene fiber 1%, 1.5% and 2% compared to the cubes without polypropylene fiber

2009-11-13 Adding polypropylene fibers to the concrete has led to a slight decrease in the compressive strength and modulus of elasticity of the specimens. The strength was decreased slightly (up to 10 percent for specimens made of 6 mm length fibers). Besides, the compressive strength has been increased with the increase in the length of the polypropylene fibers. The compressive strength of 19 mm fibers concrete is almost equal to the control concrete.

2019-1-10 Asad and Majid considered adding a great deal of PPF fibers have little influence on the compressive strength (50 mm long PPF fibers with 5% volume fraction), or even reduce the compressive strength (more than 1% volume fraction), but if lowering the content of fibers, it may enhance the compressive strength of concrete , .

2021-3-16 polypropylene fiber reinforced concrete were established and compared with standards. The study suggested the significant improvement in compressive and tensile strength for concrete mixes reinforced with polypropylene fibers. The samples with added polypropylene fibers of 1% and 1.5% showed better results in comparison with the others.4

For cement mortars the reinforcement techniques by randomly distributed short fibers, contribute highly to their micro-cracking stabilization and to improvement of their flexibility and tensile strength. Among the wide different types of short fiber reinforcement that have been used in the past for mortars, those made of steel, polymers and natural fibers dominate the area.
